If Steam Is Coming from Your Engine:
A
Steam from an overheated engine can bum you badly, even if you just
open the hood. Stay away from the engine if you see or hear steam
coming from it. Just turn it off and get everyone away from the vehicle until
it cools down. Wait until there is
no
sign of steam or coolant before opening
the hood.
If you keep driving when your engine is overheated, the liquids in it can
catch fire. You or others could be badly burned. Stop your engine if
it
overheats, and get out of the vehicle until the engine is cool.
